Hydroxamic acid-modified peptide microarrays for profiling isozyme-selective interactions and inhibition of histone deacetylases
Current histone microarrays cannot be used to directly study the transient interactions of histone deacetylases (HDACs). Here, the authors show that hydroxamic acid-modified microarrays can capture HDACs, provide insights into their substrate specificity, and serve to develop peptide inhibitors.

SARS-CoV-2 proteome microarray for global profiling of COVID-19 specific IgG and IgM responses
Currently very little is known about how our immune system responds to SARS-CoV-2 infection. Here the authors generate a SARS-CoV-2 proteome microarray for profiling of IgG and IgM responses to COVID-19 in patients and find significant responses to ORF9b and NSP5, as well as the S1 and N proteins.

Plasmonic substrates for multiplexed protein microarrays with femtomolar sensitivity and broad dynamic range
Protein microarrays are useful both in basic research and also in disease monitoring and diagnosis, but their dynamic range is limited. By using plasmonic gold substrates with near-infrared fluorescent enhancement, Tabakman et al. demonstrate a multiplexed protein array with improved detection limits and dynamic range.
